Method for the generation of oscillating scattered light intensities for the determination of a particle property vector.

We present a method for particle characterization by analyzing the light scattering from a single particle using a shaped light beam, whereby the polarization of the light beam is modulated in time. As a result, light with oscillating polarization is scattered by the particle, which offers enhanced signal evaluation benefits. First, the frequency of the high-frequency component provides an improved differentiation of the signal within a continuous flow.
